I can't get my Galaxy S4 to sync the local files saved on my Mac to be playable on it. When I go to the devices tab on my Mac, it will not recognise that my Galaxy S4 is connected to the same wi-fi network, but I can still control songs playing on my Mac from my S4 and vice versa. I can create playlists that contain local files, but when I switch it to "available offline" on my S4, it will just wait and say "waiting to download" without downloading ever. I have tried uninstalling the app on my S4, as well as clearing the cache and saved data, but it did not work. Has anyone found a solution to this issue? I am using the latest software on both of my devices (apps and operating software).
